Try about 25 miles at the speeds you usually ride at.. cut the engine and coast into drive or garage...They don't took all that bad...Might be the mods...Is that injection?
Looks pretty normal to me, the splatter you get is sometimes the additives in the fuel you buy. My$.02 Paul B
It looks a little rich, but that isn't a terrible thing for an air-cooled engine. It runs cooler. It's the popping on decel that has me a little stumped. That normally means lean mapping in the lower rpm ranges. Perhaps that is where you should concentrate your efforts. My Vintage was a handful before I got the closed loop (low rpm) portion of the FI mapping recalibrated. The ethanol laced gasoline doesn't help, as E10 produces about a 3.5% leaner mixture. Either enlist Beetle's assistance or get a re-flash from Guzzi-Tech.
based on your photo, I guess mine have been a little rich on my Carb Sport 1100...
I've been told that if using fuel with ethanol will not give the same reading on a plug chop as when using straight gasoline. Best way would probably weld in a bung an run a A/F meter and see the state of the fueling truly is.
Rocker, that's a bit greasy...
Without having the plug in my hand..The upper one looks ok for a hard run if you're using non ethanol fuel.. But the ground strap is discolored completley ? The lower run shows some mixture problems that might be caused by other factors...It's injected with one throttle body or two?
Manifold rubber boot leak?? Just a thought.Tom
